8711

The measurement principle of the Rosemont 8700M series electromagnetic flowmeters is all based on Faraday's law of electromagnetic induction. The sensor generates a magnetic field through the excitation coil. When the conductive process medium flows through the sensor, it cuts the magnetic field lines and induces an electromotive force in a direction perpendicular to the magnetic field and the flow direction. The magnitude of this electromotive force is directly proportional to the fluid flow rate. After the electrodes installed on the sensor tube wall detect this voltage signal, the transmitter converts it into a standard electrical signal proportional to the flow rate. So as to achieve precise measurement of volumetric flow rate.

The flangeless design of the Rosemount 8711 Wafer Magnetic Flow Meter Sensor makes it an economical, compact and lightweight alternative to flanged magnetic flowmeters. Choose from a wide range of rugged liner and electrode material options compatible with virtually all applications, from highly corrosive liquids to fibrous slurries often considered difficult to measure with other devices. For easy installation, alignment spacer kits are provided with every 8711 meter to center the sensor in the process line.
